Consider the following frequency of demand and random numbers:
$$\begin{array}{l}
\begin{array} { c c }
&\text { Relative }\
\text { Demand } & \text { Frequency } \
\hline 0 & 0.15 \
1 & 0.30 \
2 & 0.25 \
3 & 0.15 \
4 & 0.15
\end{array}
\end{array}$$ Random numbers: 0.13, 0.81, 0.53.
-If the simulation begins with the second random number, the simulated value for demand would be:
A) 1
B) 2
C) 3
D) 4

Quizplus · Accepted Answer

The cumulative frequency is used to map random numbers to demand values. The cumulative frequencies are 0.15 (for demand 0), 0.45 (for demand 1), 0.70 (for demand 2), 0.85 (for demand 3), and 1.00 (for demand 4). The second random number is 0.81, which falls between 0.70 and 0.85, corresponding to a demand of 3.
